DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a magnetic activated water device.

[0002]

2. Description of the Related Art There is known a magnetic water activation device which is mounted around a water pipe to activate water flowing in the water pipe by magnetism from a permanent magnet. 2. Description of the Related Art A conventional magnetic water activation device includes a permanent magnet held by an expandable and contractable magnet holding member made of rubber or having a rubber portion at a part in a circumferential direction and having an annular cut at one place in a circumferential direction. Alternatively, a plate member is provided across both ends of a pair of magnet holding members holding permanent magnets, and ends of the plate member and the magnet holding member are fixed by screws or the like. When attaching the conventional magnetic water activation device to the water pipe, expand the magnet holding member using the elasticity of rubber,
The magnet holding member is inserted into the water pipe through the cut, and the hand is released to elastically deform the magnet holding member toward the water pipe by using the elasticity of rubber. Further, in the case where the plate member is passed, the plate member is detached from the magnet holding member, fitted into the water pipe, and then the plate member is attached to the magnet holding member again and fixed with screws.

[0003]

However, the conventional magnetic water activation apparatus has the following problems. In the case of mounting using the elasticity of rubber, the outer diameter of the water pipe varies depending on the nominal diameter of the water pipe, and in the case of a thin water pipe, even if the magnet holding member is mounted on the water pipe,
There is a gap between the inner diameter of the magnet holding member and the outer diameter of the water pipe, and the magnetic water activation device is shaky with respect to the water pipe. It is not easy to attach the magnetic water activation device to the water pipe. In the case of mounting using the elasticity of rubber, a considerably large force is required when the magnetic water activation device is attached to a water pipe and when the magnet holding member is expanded using the elasticity of rubber, and the water supply of the magnetic water activation device is required. Installation work to the pipe is not easy. Further, when the plate member is passed, the screw must be removed or tightened when the plate member is removed or attached, which makes the operation complicated and one-touch installation and removal cannot be performed. An object of the present invention is to provide a magnetic water activation device that can be attached in close contact with a water pipe (can be attached without shaking) and can be easily attached to a water pipe.

And a pair of magnet holding members, wherein the pair of magnet holding members is such that the distance between the cylindrical concave surfaces of the pair of magnet holding members is equal to the outer diameter of the smallest diameter water pipe among household water pipes. Between the closed position, which is smaller than that, and the open position, in which the distance between the open / close side ends of the pair of magnet holding members is equal to or larger than the outer diameter of the largest diameter water pipe among the domestic water pipes. Wow,
A magnetic water activation device that can be opened and closed. (2) The magnetic water activation device according to (1), further including a spring that connects the pair of magnet holding members and urges the pair of magnet holding members to rotate in a closing direction. (3) The magnetic activated water device according to (1), further including a core rod having a common axis with the rotation axis. (4) The magnetic water activation device according to (1), wherein the jig comprises a scissor-like jig having a pair of arms rotatably connected around a jig rotation axis.

[0005] In the magnetic active water device of (1) to (4),
A pair of openable and closable magnet holding members rotatable around a rotation axis is provided, and the distance between the cylindrical concave surfaces of the pair of magnet holding members is a household water pipe. A closed position that is smaller than the outer diameter of the smallest diameter water pipe, and an open position where the distance between the open and closed ends of the pair of magnet holding members is larger than the outer diameter of the largest diameter water pipe among the domestic water pipes. It can be opened and closed in between, so it can be attached in close contact with the water pipe, it can be mounted without shaking, and a pair of magnet holding members can be attached to and detached from the water pipe through the open / close side end can do.

When the core rod 30 is provided, the portions of the magnet holding members 11 and 12 facing the core rod 30 are formed in an arcuate concave shape.

The jig 20 is a scissor-like jig having a pair of arms 21 and 22 rotatably connected around a jig rotation axis 23 different from the rotation axis 13. When the pair of magnet holding members 11 and 12 are opened and closed by the jig 20,
One end of each of the arms 21 and 22 is connected to a pair of magnet holding members 1.
Engagement portions 19 formed at the opposite ends of the opening and closing side end 17 of the first and the second side 12 are engaged. When the engaging portion 19 is formed of a hole or a groove, the shape of the engaging portion 19 is determined by the engagement side ends 21a and 21b of the arms 21 and 22 when the jig 20 opens and closes the magnet holding members 11 and 12. It is larger than the engagement side ends 21a and 21b so as not to be carried out.

The distance to the ends 21b and 22b is large. When the opening and closing force is applied to the opposite ends 21b and 22b by hand, the opening and closing force of the engagement side ends 21a and 22a increases by leverage. It is supposed to be.

The distance between the ends 21b and 22b of the jig 20 is reduced when the opening and closing ends of the magnet holding members 11 and 12 are opened.
The open / close side ends of the magnet holding members 11 and 12 can be opened with one hand and one touch by applying a gripping force to the hand 22b, and can be attached to and detached from the water pipe 15.

The arms 21 and 22 may be bent substantially at right angles in the lateral direction. In this case, the magnet holding members 11 and 12 are placed on the water pipe 15, and the engagement side ends 21a and 22a of the arms 21 and 22 are placed on the magnet holding member 1 from above.

The engaging portions 19 of the rotating shafts 1 and 12 move in a direction approaching each other.
3, the open / close side ends 17 of the pair of magnet holding members 11 and 12 rotate about the rotation axis 13 to the side away from each other, and the open / close side ends 17 open. The magnetic water activation device 10 descends by its own weight, and the water pipe 15 passes through the open / close end 17 and enters the cylindrical concave surface 16 of the magnet holding members 11 and 12. In this state, the arms 21, 2
When the force applied to the end portions 21b and 22b of the second member is released, the pair of magnet holding members 11 and 12 rotate in the closing direction around the rotation axis 13 by the biasing force of the spring 14, and adhere and hold the water pipe 15 in close contact. I do. In this state, the jig 20 is connected to the pair of magnet holding members 1.
